摘要

A method of fabricating a catheter shaft having one or more guidewire ports (34) is disclosed which includes the steps of cutting the wall of a first shaft portion (28) to create an opening defined by the wall of the first shaft portion, inserting the proximal end of an inner member (62) through the opening defined by the wall of the first shaft portion, inserting the distal end of the inner member (62) into the lumen of a second shaft portion (30), inserting the bonding end of the second shaft portion into a lumen defined by first shaft portion, and bonding the bonding portion (54) of the first shaft portion (28) to the bonding portion (52) of the second shaft portion (30).
